A scam in which a project's creators raise funds or attract liquidity and then abandon the project, taking the money.

Rug pulls are common among newly launched tokens on dexes, where anyone can create a token and a market for it in minutes with no review and no gatekeeper.

The name suggests a single dramatic moment, and some are. Many are slower: liquidity thins over weeks, the team stops posting, and the token drifts to nothing without any single event to point at. Both leave holders with an asset nobody will buy.

How it works

Several distinct mechanisms travel under the same name.

  1. Liquidity removal. The creators supply the trading pair themselves, then withdraw the pooled assets. Buyers are left holding tokens with nothing on the other side of the market. See liquidity pool.
  2. Malicious contract code. The token contract contains a function letting the deployer mint unlimited supply, block selling, or take an arbitrary fee on transfers. A token you can buy but cannot sell is a honeypot token.
  3. Insider distribution. No trick is needed if the team holds most of the supply. They sell into whatever demand promotion creates, which overlaps with pump and dump.
  4. Abandonment after fundraising. Money is raised for a product that never ships and the team disappears.

The observable warning signs are consistent: pooled liquidity that is not locked or is locked briefly, an anonymous team with no accountability, a contract with a mint or blacklist function, supply concentrated in a few addresses, and promotion that arrived before any product.

Example

Illustrative. A token launches with $50,000 of liquidity supplied by the deployer. Promotion brings buyers, and $400,000 flows into the pool over two days as the price rises.

The deployer removes the pooled position, taking the accumulated assets. The pool is empty. Holders own tokens with no market: not tokens worth less, tokens with no bid at any price. There is no venue to sell on because the venue was the pool.

Checking beforehand would have shown the liquidity was not locked and that a single address controlled it. Both facts were public on chain the whole time, which is the frustrating part.

Why it matters when you buy

The defense is entirely in what you check before buying, because nothing can be done afterwards. Whether liquidity is locked, how supply is distributed, and what the contract permits are all readable on chain in a few minutes. Verifying a token contract walks through it, how to spot a crypto scam covers the promotional signals, and Buyability covers assets with actual exchange listings.

honeypot token — buyable but not sellable; liquidity pool — what gets drained; pump and dump — the manufactured demand variant; memecoin — the usual category; smart contract audit — reviews the contract's powers; token approval — the permission scammers also abuse.

Questions

How do I check before buying?

Look at whether pooled liquidity is locked and for how long, how supply is distributed across addresses, and whether the contract has mint, blacklist, or transfer-fee functions. All of it is on chain and takes a few minutes.

Does an audit prevent a rug pull?

No. An audit reviews code quality on a date. It does not stop a team that holds the liquidity from removing it, and a badge on a website is not evidence an audit happened.

Can I recover funds afterwards?

Almost never. Transfers are final, most teams are anonymous or offshore, and no intermediary sits in the transaction to reverse it. Reporting is worth doing, and it rarely returns money.

Guides that use this term

  • How to Verify a Token Contract Address Before You Buy

    A token's contract address is its only real identity, so verifying one means getting the address from the project's own official channel, confirming the same address independently from a second source, and checking on a block explorer that the contract is what it claims to be before you trade against it.

  • What Is a Memecoin, and Why Most Lose Their Value

    A memecoin is a token whose price rests on attention rather than on revenue, a product, or a claim on any asset, and the structural reason most end up worthless is that attention is the only thing holding the price up and it always moves on to something else.

  • Centralized vs Decentralized Exchanges: Which Should You Use

    A centralized exchange holds your coins and your identity documents but lets you buy with a bank transfer or card, while a decentralized exchange requires no account and never takes custody but can only swap crypto you already own, so most people start on the first and use the second for assets it does not list.

  • How to Spot a Crypto Scam Before You Send Money

    Nearly every crypto scam ends with you sending funds to an address that cannot be reversed, so the defense that works is to stop at that moment and check three things, who contacted you first, whether you found the platform yourself, and whether the promised return is possible.
